Study Notes

Classical Concept of Validity: Trinitarian View

Validity refers to the judgment or estimate of how effectively a test measures its intended purpose.
Judgments are based on evidence regarding the appropriateness of inferences drawn from test scores, characterized as "acceptable" or "weak."

Types of Validity

Content Validity
- Assesses if a test adequately samples the behavior it aims to measure.
- Example: An assertiveness test should encompass a wide range of assertive behaviors.
Criterion-related Validity
- Evaluates a test's score against a standard, known as the criterion.
- Concurrent Validity: Compares test scores obtained simultaneously to determine correlation with another established test.
- Predictive Validity: Assesses how well a test's scores can predict outcomes or measures in the future.
Construct Validity
- Viewed as the "umbrella validity," encompassing all other forms of validity.
- Evaluates the appropriateness of inferences based on the test scores regarding the underlying construct.
- Two subtypes include:
  - Convergent Validity: Correlation of test scores with other measures of the same construct.
  - Discriminant Validity: Differentiates between distinct constructs to confirm distinctiveness.

Inference and Validation

Inference is the logical conclusion drawn from test scores.
Validation involves the gathering and evaluation of evidence to confirm validity.
Test developers are responsible for providing validity evidence within the test manual.

Criterion

Serves as the standard for evaluating test scores, addressing its purpose and context.
Example: When examining athleticism, membership in a health club can be a validating criterion.

Predictive Validity

Obtains test scores at one time, with criterion measures gathered later.
Measures the accuracy of test scores in predicting future behavior or outcomes.
Important factors for evaluation include validity coefficients and context for decision-making.

Incremental Validity

Refers to the additional value that comes from using multiple predictors in assessment.
Determines the effectiveness of supplementary predictors based on the situation.

Misses During Testing

False Positive: Incorrectly predicts a characteristic or attribute is present.
False Negative: Incorrectly predicts a characteristic or attribute is absent.

Evidence of Homogeneity

A valid test measures a single construct.
Test scores may vary predictably based on age, time, or experimental manipulation.
Differences between pretest and posttest scores support the construct's validity if they align with theoretical predictions.
